Device backup not working correctly due to mismatch in serviceName used.
Rest APIs should return 'serviceName'. UI should use this service name in 'device-config/backup' call
UI should display value from 'lastBackupDate' for "Last Backup" column
UI should accept 202 response from 'backup' API call and display 'successToast'
UI should only display "Backup Now" when a single item is selected (no multiple backups at this time)
Fixed a file download issue, downloads should now work correctly with actual data whether single or multiple (tar.gz)
